Do oxygen bar do anything?
Or are they just sort of a new-age beneficial gimmick?
Answer:
Yea. They are amusing. I would probably pay to see a personage
paying to breath in oxygen newly for the amusement I would
get out of it. Every presently and then I'd consent to out a gut busting laugh.
They flash the owner's pockets...
We evolved to breathe the 20% or so oxygen content in our atmosphere over thousands of years (or God created us to, blah blah... everyone get political on here at the drop of a hat) we need not breathe more.
oxygen bar do nothing. as it is the human body does not use adjectives the oxygen in the atmosphere (which is why cpr works, u breath a small % of oxygen in2 them) let alone when near is 100% oxygen being inhaled
apparently too much pure oxygen is unpromising for you
